I am having this exact issue, I'm upgraded to 7.0.220, I've tried proxy on and off, I've tried dhcp required on and off, and I've even tried dhcp server override set and off. And every combo of them and I can not get it to pass dhcp at all, exact same messages as the OP.
Except mine start with
*DHCP Proxy DTL Recv Task:
even when proxy is off.
My DHCP server is a cisco 3845, and I do not see the request getting to it to the WLC is dropping it and I can not figure out what "DHCP dropping packet (no mscb) found" means. Specifically mscb so I'm out of options, but I really need to get this media bridge working.
Did the OP ever get this working? does anyone else have any ideas I can try?
it is an old thread without a proper solution, perhaps someone can help.
I am having the same problem as described originally. Connectivity: Printer ==ETH==> Cisco/LinksysWlanBridge ==WiFi==> Cisco 3802i (MobilityExpress) ==ETH===> Gateway/DHCPServer.
I can see DHCP discover packets arriving at my DHCP server and the server properly replies. However, the reply packets never reach the Printer. I had this working with an older enterprise 3Com access point, but when I recently changed to Cisco 3802i it does not work any more. DHCP proxy or bridge mode on the interface does not make any difference. There is no global DHCP setting on the Mobility Express WLC.
